To all whom itv may concern.

Be it known that I, PERLEY R. GLASS, a citizen of the United States,residing at Quincy, in the county of Norfolk and State of Massachusetts,have invented an Im rovement in Stock-Feeding Mechanism for achines forSetting Lacing-Studs, Eyelets, Rivets, &c., of which the followingdescription, in connection with the accompanying drawings, is aspecification, like characters on the drawin s representing like parts.I

he chief aim of my present invention is to provide a clamp for stock inwhich eyelets, acing-studs, or lacing-hooks areto be set, which clamp isadapted to hold the stock clamped throughout the 0 eration of setting aplurality of eyelets, stu s, or hooks in succession. The clamp ismovably sustained and suitable means are provided for intermittinglymoving it forward relative to the settingKdeviceS, so that after oneeyelet, stud, or hoo has been set the clamp andthe stock carried therebyis moved forward to osition the stock correctly for receiving t e nextsucceeding eyelet, stud, or hook. Suitable means are also provided forregulating the distance that the clam is fed forward at each step. Theclamp wi be moved intermittingly or between each setting operation witout unclamping thestock and when the proper number of setting operationshave taken lace the clam will be returned automatica to its startingposition and will be opened y the operator that new stock may beinserted.

In the following descri tionI will refer to l iare to be set in thestock as lacing-studs, though it will be understood that my inventioncan be used for setting eyelets, hooks, or any similar devices. Figure 1of the drawings in side elevation represents my inventionin one of thebest forms now known to me with sufiicient clearness to enable the sameto be understood; Fi 2,, aplanview of some of the parts shown 1n 1g. 1,-and Fig. 3 is a left-hand end view of the arts shown in Fig. 2.

T e framework or bed A, the overhanging head A, sustaining the top set Athe hookca g plunger A guided in a hearing A of the [Zed or framewoi'k,and the main shaft A are and may be as in United States Patent N o. 734,823, July 28, 1903; but instead of the Specification of LettersPatent.

parts so far referred to I may use an known equivalent devices forsetting lacingooks or for setting eyelets or inserting rivets in stock.I have added to machinery of the class described means which I will nowparticularly describe. I

I erect on the bed A'through, as shown two studs B B a work-sup ort B,represented as grooved longitudinal y to constitute a guideway for thereception of the lower memr a of astock-clamp, said lower member havingcoacting with it an upper member a, carried by a rod 0, surrounded by aspring 0., that, acting through a nut (13 on said rod, normally keepsthe upper member of the clamp pressed toward the lower member thereof,that the clam may hold and clamp the stock. To open t is clamp, I employa lever a, pivoted at a", that may be acted upon through. a link a, anda treadle (not s own) to move said lever in a direction to raise the roda preparatory to inserting into the clamp stock and removing stocktherefrom.

The upper and lower members of the clamp each have a long slotconstituting a throat studs or other devices is released after eachsetting operation and again clamped that the stock may be moved fartherfor the reception of another stud or device.

I have provided means whereby the clamp may be moved between eachsetting operation for exactly the same distance, and when thepredetermined number of lacing-studs or devices have been set in thestock the clamp will be automatically returned to its starting positionthat the operator may by his footopen the clamp to receive new stock;but it will be understood that by the employment of usual automaticstarting and stopping means controlling the operation of the main shaft,means common in machinery for inthreaded shank of a ban opened when thelatter has been returned to its starting position.

the upper member of The rod a, the clamp, enters a hole in the end of alever 6 (shown as slotted at b) to receive a fulcrumblock b, fittedslidably in said slot, said block being entered by a stud b in afeed-spacing device 0, shown as a lever having its fulcrum at c on theframework. This lever is bored at its outer end and tap to receive theiece c, surrounded loosely by a block 0, aving a point 0', said blocbeing acted upon at its inner side by a spring 0, said spring serving toforce said block frictionally ainst a curved indexplate 0 attached to te framework A by screws 0. This indexlate will in practice have a seriesof lines (shown in Fig. 2) that will be properlynumbered to iiidicatewhere the point 0 of the block shall stand to insure the insertion oflacing-studs at just the proper distance apart according to the size inlength of a shoe-upper.

The lever b with its attached link I) and the elbow-lever b constituteone form, of means intermediate the clam and the clamp-actuator to bedescribed, y which to move the clamp intermittingly, a suitable spring bbeing employed to maintain the e bow-lever b and connected parts inoperative relation to the actuator; but instead of the particulardevices b b b I may employ any equivalent means controlled by theactuator and moved intermittingly to feed the. clamp, as I will nowdescribe. I

The actuator is culiar in its shape and operation, and as have hereinshown the same it consists of a cam (I, ha as illustrated, aconstruction whereby the clamp ma be moved intermittingly step by ste insue way as to insure the sett' of four acing-studs, each movement beingfollowed by a dwell in the clamp of suificient length to enable a hookto be set. For instance, while the roller 2, carried by the lever binthe retation of the actuator, contacts with the point 3 thereof theclamp will occu ya position to insure, say, the sett' o the firstlacing-stud of a set of four stu s, and while the roller is moving fromone of said oints 3, 4, 5, and 6 to another of-said points t e clampwill be moved for the predetermined distance and the setting will takeplace while the roller travels on the circular portion of said parts 3 45 6. It will be noticed that theradius of each cam portion 3 4 5 6 issuccessively longer and that the actuator, shaped as illustrate 'ves anadditional movement to the clamp 1n the same direction step after step,and when completing the cycle of operations. 'and the four studs, asherein provided for, have'been set the roller 2 again comes onto-thepart 2 of actuator.

In setting four eyelets in succession during a movement of the clampintermittingly in the same direction without releasing the stock theshaft carrying the actuator will be rotated once to four rotations ofthe main shaft A, said main shaft having a pinion e -.o;:;wat00tlledgeare0ntlleShaftca1Tyt l e actuator. lo vary the distancebetween the first stud to be set and following studs of the series to beset, I move the feed v the fulcrum of t e lever b.

e framework has a slot f, in which the rod (1. travels under the controlof the lever b, and in the travel of the clamp the lower end of the roda retires from contact: with the end of the lever a, and to prevent saidlever from a wro 'tion when relieved from the contactwit each of saidrods I have connected with said lever a spring f of a strengthsufficient to maintain said lever in contact with a stop f at all timeexcept when said lever is to be moved by an ovegilowering force appliedthrough the tre e referred to, as w en'lifting the up r member of theclamp from the lower membzr thereof for the rece tion' of new stock.

Having descri my invention, what I claim, and desire to secure byLetters Patent, is

1. In a machine of the class described, a clamp for engaging oppositesides of the stock, setting devices to set a series of studs in thestock thus clamped, and automatic means to feed the clamp and stockintermittingly as the various studs of the series are set, and means forret the clam to its initial position after a p etermine number oflacing-studs have been successively set.

2. In a stud-setting machine, the combination of a clamp for engagingopposite sides of the stock, sai clamp being formed of. two

supe members, the upper member being provided with a slot of a le hgreater than the length of the row of stu to be set,
